Flowline LR25 Specifications

EchoPulse LR25 Pulse Radar Level Transmitter

® ®

Product

Application

The general purpose 6.3 GHz. pulse radar level transmitter

provides continuous level measurement up to 114.8’ (35m) with a

4-20 mA signal output, and is congured via its integral push button

display module. The non-contact liquid level sensor is intended for

chemical and petroleum storage or process applications in above

grade metal or reinforced concrete tanks or below grade tanks of

any material. Select this sensor for harsh application conditions

with corrosive or low dielectric media, heavy surface foam or

agitation, higher pressure, steam, condensation or vapor, and

installation in a ange tting. Due to the wider beam angle, special

attention should be given to ensure that the sensor is located with

unobstructed measurement space.

6.3 GHz. pulse radar is unaffected by most foam and agitation

12” (30cm) dead band enables utilization of the entire tank

LCD displays level in feet or meters with percent of span bar

Optional display mode indicates the echo signal return curve

Auto-temperature compensation for accurate measurement

Fail-safe diagnostics with selectable signal fail-safe outputs

Recognition, storage and rejection of false echo signal returns

Rugged IP67 aluminum enclosure with polycarbonate window

Success

Based upon the type of inow and

system design, not all wastewater

neutralization processes are the

same. Here, a LR25 is mounted

on a 12’ neutralization tank with

agitation, foam and vapor. Its wide

beam, low frequency, 6 GHz. pulse

radar measurement is unaffected by

most process conditions, and is the

right choice for difcult applications

where other level technologies may

not perform reliably.
